4Material Faces, of which the following is a specification. l

The present invention relates to improvements in matrices for casting faces in metal strip material such as are used on a type or slug casting machine.y

At present it isthe practice to provide a separate matrix for each style of face.

The object of the present invention is to provide aV matrix having a single body or `holder and a casting portion which can be varied so that a large number of different styles of printing faces can be cast thereby, thereby effecting a great saving.

In the accompanying drawing, Figure 1 is I a plan view of the matrix; Fig. 2i is a perspective view thereof; Fig. 3 is. a longitudinal sectional view on the line 3-3 of Fig. 1; Fig. 4 is a cross-sectional view on the line 4 4 of Fig. 1; Fig. 5 is a perspective view of a packing piece used therein; Fig. 6 is a similar view of a packing piece used on the side of the matrix opposite to the packing piece shown in Fig. 5; Fig. 7 is a similar viewk of a space liner; Fig. 8 is a similar lview of a face liner; Fig. 9 illustrates a number of different faces selected from the whole number which can becast. from La singley matrix of my invention.

` seen that my improved matrix is compounded of several different pieces. `The main piece is a holder 1, rectangular in plan view, and the length of which is identical with those at present in use in the mono- Vtype machine, while the width is preferably a trie less, as .395 inch.

The middle portion of said holder is recessed to aconsiderable depth, the ends .2 of said recess being undercut. In this recess is inserted on one side a packing piece 3 of constant width, namely', .1585 inch. This packing piece, as well as all the pieces hereinafter described which are contained in said recess, is of the same length as the recess and is formed with beveled ends 4 to iit snugly against the undercut ends of the recess. The packing piece 3 is preferably inserted rst in the recess. The casting face of the matrix is then made up by means of space liners 5 and face liners 6. `These space liners and face liners vary in thickness according to the face which it is desired to cast from the matrix, the space liners being, of course, of greater depth than the face liners. Suppose that it is required to cast the face indicated at 9a in the series of faces 9 illustrated in Fig. 9, there is placed'in the holder 1 by the side of the packing piece 3, first, a face liner 6 of the thickness of about .005 inch,

then a space liner 5 of .0138 inch thickness,

then a face liner 6 of .0138 inch thiclmess, then a space liner 5 of .0138 inch thickness, and then a face liner 6 of about .O05 inch thickness.

One .or more side packing pieces 7 are then inserted in the recess in the matrix. The thickness of this packing piece or pieces 7 depends upon the face required, and I provide, for thus closing the matrix, packing pieces of three different thicknesses, namely, .1585, `.083 and .0553. Thus, a matrix having a two--point facewould be closed by using packing pieces of .1585 and .0553 inch in thickness. In. all cases packing pieces 7 are selected which will, with the packing piece 3 andthe liners 5, 6, have a combined thickness of .4 inch, so that packing pieces 3 and 7 project slightly beyond the sides of the holder` 1, andthereby they are pressed inward by the packing pieces of adjacent matrices, so that the liners and packing'pieces fit tightly against each other.

One end of the holder 1s at the same level at the top as the packing pieces l3 and .7,

while the other end is recessed to provide a surface 8, which, though in .approximately the same plane as the casting face of theis inverted for casting, or, in other words,

necessary that it should extend throughout a width slightly greater than the thickness of the face liner, its only object being to permit the ready passage of the face cast from said face liner.` Thereby a rule face can bev formed of any length by successively cast--y ing the several sections thereof and moving them past said surface 8. Face and space liners may be provided of any thickness desired, but I propose to provide `with one holder .the following face liners, namely three of a thickness of'one-third of a point; three of one-half of a point, three of 1 point; two of 2 points; and one each of 3, 4, 5, 6, 8, l0 and l2fpoints; and the following space liners,l namely: three of the thickness of .one-half yof a point, three of 1 point, and three of 2y points.k TWith ,this outfit, faces. can becast of `almost an .infinite number of designs. i

It will be seen .that the compound matrix herein. describedfwhilecapable yof castingV a great variety of faces, 9, some of which are illustrated in Fig. .9, can be made comparativelyv cheap, asthecost of the holder is not great, and all the remaining. .parts canv be madeat comparatively small expense.

As shown in Figs. 2 and 3 of the drawing, thereis a slight-.taper of .about .002 ofan inch, in the thickness of the mediate or thin portion of the holder l, therear end of this thin :portion beingthinner thanv the front end thereof. The liners are of uniform depthlthroughout.. The space in which. the printing face` is cast extends only through the rear half of the length of therecess in the holder, each casting lafter-it is made, be-f ing moved tothe front half of said recess to` make roomI for. the next casting. It results froml the abovefmentioned taperfthat the rear portion of .eachcasting is about .001 of an inch higher than its front portion. But, in being moved to .the front portion of the recess, said rear portion of the printing face is pressed or smootheddown, so that the rear portionof an advancing castingand the front portion of a succeeding casting, are, as it is termed burnished together asv the rule is pushed through thematrix, thereby-` insuring a,l perfectly continuous line of any length in the printingface however many castings maybe usedl to formisaid ,line or printing. face. The sameresultcan be obtained by` making the thin portion of the holder uniform in thickness and-tapering the Y liners toward the rear end. This construction would, however, be more expensive and inconvenient than the one here shown.

I claim:

l. A compoundl matrix comprising a holder having in its face a longitudinally extending recess and a face liner and side packing 'pieces extending longitudinally in said recess, said holder being provided withv means for lretaining said liner and packing pieces in said recess, and an end of the holder having the surface which is most 7@ nearlyy in' thesame plane as the casting-face f" of the face liner suiciently near the opposite side of the holder to permit the rule face cast by said face liner topassiinia lon-fc4 gitudinali direction by said portion-sof' the 80 surface without contacting therewith.
